Description
Technical field
The present invention relates to a kind of inspection well cover, especially a kind of inspection well cover with alarming device.
Background technology
It some times happens that the leakage of material, the material of leakage can be discharged with drainage in chemical plant.Some materials exist
Reacted in circulation passage, produce inflammable and explosive gas, gas typically can be to circulation at inspection well cover.If having near inspection well cover
After being contacted with naked light violent detonation can occur for fire operation, inflammable and explosive gas.
The content of the invention
The present invention provides a kind of inspection well cover with alarming device, to solve flammable explosive gas and field operation in inspection shaft
The problem of detonation occurs for naked light contact.
To solve above-mentioned technical problem, the present invention provides the inspection well cover with alarming device, wherein:Well lid by upper chamber,
Lower chamber and cover plate composition, are separated by dividing plate between upper chamber and lower chamber, are stamped cover plate in the upper chamber, cover plate with it is upper
Pin-joint piece on the wall of floor room side is hinged, and the space of upper chamber is built with warning air bag, the interior promising warning of storage of described lower chamber
The feeder of air bag supply, be power electricity consuming apparatus battery, controller, described controller respectively with battery, peace
Magnetic valve at feeder gas outlet, the connection of the gas-detecting device on well lid bottom wall.
Preferably, air bag top is provided with warning lamp, and described warning lamp is connected with controller.
Preferably, fluorescence warning bar is posted on bladder sidewall.
Preferably, the air bag after inflating expanded is cone.
Preferably, Electronic flute is installed on cover plate inwall, Electronic flute is connected on controller.
Preferably, feeder is connected with nitrogen header pipe.
Preferably, solar panel is installed, solar panel is connected with battery on cover plate.
Using technical scheme, after flammable explosive gas is exceeded in inspection shaft, air bag can be opened, neighbouring construction
Personnel or the tour personnel at scene can timely be found the abnormal situation, it is to avoid inflammable and explosive gas is contacted with naked light in inspection shaft
Generation detonation.

Embodiment
To make those skilled in the art be better understood from technical scheme, specific embodiment is given below
The present invention is made further instructions.
As shown in Figure 1, the inspection well cover with alarming device, wherein:Well lid is made up of upper chamber, lower chamber and cover plate, upper strata
Separated between room 2 and lower chamber 3 by dividing plate 5, cover plate 4, cover plate 4 and the hinge on the side wall of upper chamber 2 are stamped in the upper chamber 2
Contact pin 6 is hinged, and the space of upper chamber 2 is built with warning air bag 7, and the promising warning air bag 7 of the interior storage of described lower chamber 3 is supplied
Feeder 8, be power electricity consuming apparatus battery 9, controller 10, described controller 10 respectively with battery 9, be arranged on
Magnetic valve 11 at the gas outlet of feeder 8, the gas-detecting device 14 on well lid bottom wall 15 are connected.
During use, after gas-detecting device 14, which is detected, there is flammable explosive gas in inspection shaft, controller
10 control magnetic valves 11 are opened.After magnetic valve 11 is opened, the gas in feeder 8 enters warning air bag 7, and magnetic valve 11 is controlled
System is filled with the amount of gas in warning capsula interna 7.Warn after the inflation of air bag 7, cover plate 4 can be held by gradual top, and warning air bag 7 is exposed to
In air, play a part of warning on-site personnel.In order to further enhance the alarming effect of warning air bag 7, the top of air bag 8
Warning lamp 12 is installed, described warning lamp 12 is connected with controller 10.After warning air bag 7 to open completely, warning lamp 12 is opened
Light is originated, the alarming effect of alarming device now can be more obvious.If posting fluorescence warning on the fruit warning side wall of air bag 7
Bar, then the alarming effect of alarming device can be more obvious.Warning air bag 7 can select different shapes according to the actual needs
Warning air bag 7 in shape, the technical program, it is preferably inflating expanded after warning air bag（7）For cone.
Sometimes workmen may be had no near inspection well cover, can not be found different the very first time after alarming device starts
Often, if installing Electronic flute 13 on the inwall of cover plate 4, Electronic flute 13 is connected on controller 10, is warned after alarming device starts
Flute 13 can send the sound, point out people's alarming device to start.
The problem of feeder 8 there may be air-tightness, during overlong time, the air pressure in feeder 8 may be too low, if
Feeder 8 is connected with nitrogen header pipe, when the air pressure in feeder 8 is too low, the gas in nitrogen header pipe can be mended
Be filled with feeder 8, maintain feeder 8 in air pressure stability, it is to avoid when detector 14 detect it is inflammable and explosive
Alarming device can not timely start after gas.
In order to avoid the battery 9 in device is because of resting period long low battery, solar cell can be installed on cover plate 4
Plate 16, solar panel 16 is connected with battery 9.
Embodiments of the present invention are explained in detail above in conjunction with accompanying drawing, but the present invention is not limited to above-mentioned implementation
Mode, in the knowledge that those skilled in the art possess, can also make on the premise of present inventive concept is not departed from
Various change.
